A former coworker once claimed I had a Superman complex because I had an Alex Ross-painted poster when Superman "returned" to his original costume.
However, she has probably never seen Fortress of Soliloquies, which is an all-Superman blog. I highly recommend it for the fan and non-fan alike; this blog is just brimming with enthusiasm, energy, and just plain fun! (And thanks for the link, pal)
And taking a cue from Nuance, I also highly recommend Tequila Mockingbird, a more personal blog. Some of the pieces, I have to admit, I wish I had written - imagine sitting over drinks with someone you barely know, and you have the kind of conversation that two people who barely know each other have. You know, where you discuss your innermost feelings and thoughts, knowing that you may not see each other again. The kind of conversations where you say to yourself, "I can't believe I'm saying this out loud." That's the kind of blog this is, and worth your time.
